Efficient LED's - reply
Jim - The most efficient light source at this time is the compact flourescent tube. Halogen is next followed by LED. So, why would I call LED's efficient? Mostly because modern LED's have the ability to provide very "white" light even at very low power levels. The 10W bulbs I'm replacing use 14X more power than these LED modules. If you ran an incandescent that low there would be very little useable light and it would be very yellowish.It's in these sort of low power applications where LEDs come into their own. A larger cluster of LED's could put out more light than a standard tungsten incandescent, and use less energy, but the advantage wouldn't be huge.Another key advantage in marine applications is the ruggedness of an LED. It is unaffected by vibration and shock. It also has a life of about 100,000 hours. That's why a few companies are working on LED anchor lights. You'll never have one burn out on you.To learn more about LED's and other light sources, checkout the CandlePowerForums (click the link below). We're a bunch of flashaholics who love LED flashlights.
